He only has a 1% effective rate if you change the definition of effective rate. I assume you're fine with making that change, but the federal government isn't currently.
Taxing unrealized capital gains isn't happening because Amazon is lobbying the federal government, it's a fundamental premise of the US tax code and starting to tax them is arguably unconstitutional (I'm not arguing it is or isn't, but I've seen arguments that it is unconstitutional from reasonable sources).
